The command-line tool the org builds and provisions with — one binary that carves a host into per-user workspaces, then ships and replaces itself.

Contributions

• Built multi-tenant host provisioning on btrfs: per-user workspaces whose binaries, code, toolchain and build directories are independently snapshottable subvolumes under soft quotas.
• Added an identity-preserving rollback that resets a workspace to clean while retaining the account, its SSH key, its overlay-network address and its limits.
• Owned release engineering — commit-anchored release tags, rolling pre-releases cut from CI, and an atomic-rename self-update so the tool rebuilds and replaces itself without corrupting the running binary.
• Validated user-supplied paths at the provisioning boundary and moved the CLI onto structured tracing.
